SATCHEL OR BAG FRAME.

SPECIFICATION forming part of Letters Patent N0. 514,890, dated February13, 1894. Application filed September 14, 1893. Serial No. 485,465.(No'model.)

To all whom it may con/cern: i

Be it known that I, FREDERICK \V. HEIL- MANN, a citizen of the UnitedStates, residing at Newark, in the county of EssexV and Slate of NewJersey, have invented certain new and useful Improvements in Satchel orBag Frames; and I do hereby declare the followlng to be a full, clear,and exact description of the invention, such as will enable others- Ioskilled in the art to which it appertains t0 make and use the same,reference being had' to the accompanying drawings,and to letters ofreference marked thereon, which form a part of this specification.

The object of this invention isto provide 'an improved device forholding the Satchelframe open, to reduce the cost of construction and tosecure other advantages hereinafter referred to.

The invention consists in the improved holdlng device, and in thearrangement and combination of the parts thereof, as herein set forthand finally pointed out in the claims.

Referrlng to the accompanying drawings, z 5 1n whlch similar letters ofreference designate corresponding parts in each of the figures wherethey occur, Figure l, represents, in plan,.one end of a bag-frame openedand embodying myimprovement, and Fig. 2 is a simi- 3o lar view,notopened so fully as in Fig. 1, and

showing the central portion partially in section, exposing to view, inelevation, the working parts and their relations to one another.

Fig. 3,.is a section taken through the line .fr

of Figi; and Figs. 4, 5 and 6, are detail views,

in elevation or plan. Y. I

In rsaid, drawings, a, designates the opposite sides 'of the bag-framewhich are constructed 1n the usual manner; and b, a housing'or cap 40which incloses the working parts and serves as a seat or bearing for oneend of a spring c.

Secured to one side of the frame is an arm, d,

which carries an annular plate e, the outer surface of which is serratedor provided with inclined projections,e, alternating with correspondingdepressions which engage, in holding relation, with an annular plate fhaving similar projections, f', and depressions and mounted upon apintle orv rivet, g,which passes through and holds the several vpartstogether,

as indicated in the drawings; said plate f, being movable on said rivetlongitudinally, and bearing against the spring, c, which serves to holdsaid plate, f, normally .in frictional contact with the plate e, as willbe understood. The outer end of the pintle gis riveted upon the frameand is hidden by a cap, h, secured to said frame; and the hinge-ends ofthe frame are separated by a washer, t', which, however, may bedispensed with, if desired, 6o as may also the arm, d, in which latterevent the annular plate e may be attached to or connected directly withthe frame, as will be understood.

As herein shown, the plates e and f have more projections than areabsolutely necessary, as one projection on each plate, properly located,would be snfcient to hold the bag o'pen to its fullest extent or to anydesired l extent, but, two or three projections will, of 7o coursebepreferable.

It will be seen from the foregoing that, as the bag-frame is beingopened or closed the teeth or projections e and f ride over or upon oneanother and into the intervening depressions automatically, the platesbeing, by the operation alternately forced apart and together, againstand by the pressure of the spring, which is sufficient to hold the frameopen when released by the hands, as will be 8o understood. l Thus thenecessity of manipulating the holding device is avoided and both handsare left free to grasp the opposite sides of the frame in the operationof opening or closing the bag, as will be obvious. 8 5

The device may be applied to either end or to both ends of thebag-frame, as will be obvious, and the operation thereof will be evidentwithout further description.

Having thus described my invention, what 9o I claim, and desire tosecure by Letters Patent of the United States, is-

1. In a bag-frame, the combination with the hinge-pin or rivet thereof,of two plates having alternate inclined projections and depressions andarranged in juxtaposition with each other upon said pin,and aspring alsomounted on said pin and adapted to automatically hold said plates inengagement with one an-y other, as the bag or frame is being opened orroo closed, as described and for the purposes set forth.

2. In a bag-frame, the combination with the hinge-pin thereof, of twoplates having alternate inclined projections and depressions andarranged upon said pin in juxtaposition With one another, a spring alsomounted on said pin, and a housing or cap, said parts being arranged inrelation to one another and to operate automatically substantially asdescribed 1o and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of September, 1893.

FREDERICK W. HEILMANN.
